Hi, almost all cheap cams have poor video quality. If you are looking for something decent, I can recommend a cam we're using, it’s called Homam. You can check out the quality of video on their site, it’s impressive.
Hi again! There are few other options, but we decided to buy this one: https://zorachka.com/homam, they have something they called true HDR, this feature really improves overall footage quality, so nice cam for regular home use even for capturing fun moments of your life.
